I had some really smart kids working for me over the summers at Canoe U. Marshall scholars, Rhodes scholars smart. I saved up miserable work for them all year and, come June, I'd give them one project each. I told they didn't have to come in, nothing. Just log their hours and send them to me every week. I'd make an estimate of how long each project should take, with a guess at what a standard dev might be. Invariably they went insane with boredom and frustration and asked for more projects.

I'm not saying my management style was exceptional, but their insight into the nature of work was: if the project bores the crap out of you, ask for two or three more. By working on the more interesting projects, you can save up willpower to tackle the dull-as-rocks first project. You might actually get through the first one faster.
